SPECIFICATION forming* part 0f Letters Patent No. 648,405, dated May 1, 1900. Application filed August 18. 1899. Serial No. 727,669. (No inodel.)

T0 @ZZ whom t may concern:

Be it known that I, SAMUEL HALTOM, a citif zen of the United States, residing at Henderson, in the county of Rusk, State of Texas, have invented certain new and useful `Improvements in Saw Setting and'Feeding Devices, of which the following is a specification, reference being had therein tol the accompanying drawings.

This invention relates to saw-setting devices, and more particularly to a construction adapted to automatically feed the saw so as to present a new surface for the action of the 'setting-punch after each operation of said punch.

The invent-ion has for one object to provide a simple and improved construction of setting device whereby the punch `will be actuated upon and positively driven byalatch carried upon the operating-lever.`

A further object of the invention is to improve the structure of feeding devices which are driven by said lever in its return movement after the Vsetting operation.

Other objects and advantages of the invention will hereinafter appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.l

In the drawings, Figure l represents an elevation of the invention. Eig. 2 is a plan. Fig. 3 isadetail of the latch for the setting-punch.

Fig. 4 is an elevation of the opposite side of the machine from that shown in Eig. l. Fig. 5 is a vertical section on the line 5 5 of'Fig. l. Fig. 6 is a detail vertical section taken at a right angle to the section shown invFig. 5, and Fig. 7 is a detail plan of the guidingplates.

Like letters of referenceindicate like parts u throughout the several iigures of the drawings.

The letter A represents a framework,which may be of any suitable configuration or construction adapted to support the parts carried thereby. Upon this framework and within guides A' an anvil B'is supported, having an operating-faceB-, and said anvil is capable of adjustment by means of the set-screw B2, journaled in the boxing A2, and the locking wrench-nut B3. O peratin gin connection with this anvil and opposite thereto is a settingpunch C, guided by the iianges A3 upon the frame A and normally held out of contact with the anvil B by means of a spring C', bearing upon a pin or stud C2.' For the purpose of operating this punch a suitable lever D` is pivoted to the frame, as at D', and carries upon its face next the punch Oa cam D2, which imparts a preliminary movement to the punch and brings the stud Cg thereon into position for` engagement with the latch E, by whichthe positive movement is imparted to the punch. The latch E is pivotally mounted upon an angle-arm D3`of the lever D and is normally forced toward the stud C2 by meansof a pressure-"pin F, seated in a casing A4, carried by the frame, and actuated by the spring F'. The face of the latch is provided with a seat E', adapted to rest upon the stud C?, and the latch is held away from the stud C2 when the lever is raised by means of apin `Cf'gwhich engages a face of the latch, as shown in Fig. 3. It will be seen that when the lever D is in the position shownV by dotted lines in Fig. l the latch E will come into contact with the stud C2, and the movement of the lever to a vertical position positively actuates the punch through the action of the angle-arm D3 and the latch E. After this angle-arm passes beyond the plane of the punch the latch is thrown out of engagement therewith and the spring C returns the punch to the position shown in Fig. l. Y *l For the purpose of simultaneouslyactuating the feeding mechanism infthe movement of the lever D the pivotal shaft D' of this lever is provided at its opposite end with a segmental gear G, the s ame bel-ing supported by an extension A5 from the frame A. This gear meshes with a pinion G', freely rotatable upon the shaft G2, which carries at its opposite ends the feed-wheel l-I. This pinion is provided with suitable sockets G3, coperating with a pawl G4, which is mounted upon a squared portion G5 of the shaft G2 and 'held in contact with the gear G by means of the sprin g G6 bearing against said pawl `and acollar G7. It will thus be seen thatV the movement of the pinion in one direction will rotate the shaft and feed-wheel through the medium of the pawl secured to said shaft,

.This recess isalso adapted rto receive the han-l Y J', vwhichA supports the journal J 3 `of the roller J ,into contact with the wall of the recess A,

while the opposite rotation of the pinion will not effect such rotation. Y The feed-WheelH, as shown, is composed ed upon the shaft G? and adapted to be adjusted by means of. set-screws H2, mounted in the opposite ends of a cross-bar H3 to Ydetermine the curvatu re of the spiral blades H'. In the operation of the feeding device one of these blades engages the saw at each move- For the `purpose of preventing a backward rotation of the feed-Wheel from any cause aspring-catch I is mounted in the .frame and adapted to be forced inward during the movement of the wheel and to springoutward into position as the end H'of oneblade passes over the same',

, For the purpose of determining the degree or extent to which .the saw may be introduced into the device a gage-wheel J has been pro-k vided, which may be of any suitable material and is mounted in a recess A6 of the frame A.
